hi there ppl,
im new to this device, just got it few days ago, but my model is the 4g/LTE/ G7105. and it comes with JB 4.3
so i've search google, you tube, xda, and few more forums and found nothing on how to root my device. i know that there is a way to flash stock KK 4.4.2 firmware of other region from sammobile website.
i really dont care about the warrenty issue, mostly i wish to debloat the stock rom and flash custom recovery.
but i have few question if someone can help
1. i rather stay with JB with this device, so if anyone have this device G7105 rooting methood and did manage to root it pls share .
2.if i do decide to flash stock KK what happens with knoks, will it have effect on device (except the ticker which i dont mind) if i want to flash stock JB back ?
3. if i flash stock KK of region like france germany or greece, and my region is israel, will it have effect on my 4g/LTE connection and other network and gps problem?
4. last question, can i change modem if the above question mean i do have problems ?
i have galaxy s3 also but i was a lot easier to handle rooting, and since its a bit of different ways i dont like to mess hardbrick my device already.
thanks for all helpers

Hi there guys I really need educating. I come from a Samsung Galaxy S to a Samsung Galaxy S 3. I know all about firmware flashing, kernels n stuff on the original Sammy G, but haven't a clue on the Samsung Galaxy S 3.
I have managed to root the bad boy (go me!) but am unsure how to carrier unlock and to flash the latest firmware. The Sammy G was carrier unlocked but my Sammy G S3 is locked to Vodafone
Can anyone point me to the files and maybe some guides so that I can procede? Also what is this business about a flash counter? I want to be able to return to original firmware if it all goes belly up! How do I backup my original firmware?
Many Thanks In Advance
Doozy,
P.S.
Who is the best Dev to follow for A) Rom and B) Kernel? I followed CyanogenMod on the Sammy G but the CM9 nightlies fpr the Samsung Galaxy S 3 seem a little immature for me at the moment.
Cheers once again
I think you don't have to backup your original firmware because you can download the stock firmwares again later, but you can do a nandroid backup (i never did this^^)
If something goes wrong, follow this guide: http://forum.xda-developers.com/showthread.php?t=1671969
About unlocking i don't know, but i think the lock will be gone if you flash any rom (but can't give you warranty, since my phone was unlocked)
You can reset the flash counter, it's called triangle away : http://forum.xda-developers.com/showthread.php?t=1494114
Im not able to say, whick rom / kernel is best, but why don't you check this thread and try some roms? http://forum.xda-developers.com/showthread.php?t=1674286
The first CM9 releases had many bugs, but they seem to be ready for all day use now (but i missed the Sammy Camera App, which is very nice )
Thank You very much for taking the time to respond I will take a look at those links.
Thanks Very Much,
Doozy
Hello guys..!
i bought this phone some other country..!
and its flashed with some custom rom..!
i am using samsung galaxy S II GT-I9100
Baseband version is I9100XXKI3
KERNEL VERSION IS 3.0.31-N.E.A.K-2.0.5x [email protected])
AND i dont know wch stock rom to download..!
right now i live in India and this mob is bought in someother conutry wch i dont know..!
is it okay to download India stock rom to it..!
can someone tell me wch stock rom i need to downad and prefer me the link too plzz..!
and also wen i switch on my mobile it shows a triangle sign below with the samsung symbol..!
so plzz help me out to flash back the stock rom..!
thnxx..!
It shouldn't matter which stock rom you flash, if it were me I'd be flashing a rom released by the carrier your currently using as the modem in it should give you good connectivity.
Nobody's going to give you links (they'd better not) when all you need to do is go to Samfirmware & spend two minutes or less using the pulldown boxes to find the rom you need. How to flash the rom ? Search. This has been covered so many times here over the past two years it ain't funny.
If you've got the warning triangle then someone has flashed non stock firmware on it at some stage. No need to worry about it unless you ever need to make a warranty claim, because removing it will involve rooting the phone (How ? Search).

so it does not matter about the contry wch we bought we can just flash a rom from samfirmware and my phone is rooted though..! and its showing triangle symbol.! so no need to worry about it while flashing my stock rom right ?
You should be able to use any stock rom from any carrier/country just fine, but as I mentioned, if it were me, I'd be flashing a stock rom released by my carrier for the reason mentioned.
If you flash stock you'll lose root, if you want it back, you'll need to re-root your phone (How ? Again, search). As mentioned, no need to worry about the triangle unless you'd need to send the phone to a service centre for a warranty claim (tho you can remove it with Triangle Away if you re-root your phone).
Hello everybody, my device is a Samsung Galaxy S Duos S7652.
I am new at this whole rooting thing, i did my first rooting to be honest yesterday and i chose PMP Ultra custom rom, because it was the best rom for my taste.
Unfortunately i didn't know about baseband compability , and my baseband version was s7562xxlj3 , and now my phone cannot receive or make calls.
I need help, what do i do??
I cant even find my original rom so i can install that, or even a custom rom that supports my baseband..
Can you please help me?
Best regards, Alkis.

I think you are mixing some definitions.
Rooting is providing root capabilities to the phone, this is a standard operation in the *nix world.
Selecting a ROM is formatting the whole system and put a new one and you probably changed the kernel (hence the baseband problem).
Fortunately the phone is not bricked (unable to boot), so my recommendation is try to check if there are other kernels/ROMs compatible and change it.
Fortunately this showed while searching: http://forum.xda-developers.com/showpost.php?p=42182649&postcount=1708

I would recommend either restoring a NANDROID backup in recovery and if you don't have a backup I would recommend searching for your devices firmware here http://www.sammobile.com/firmwares/1/ and then flashing it via Odin. Let me know if you still have questions I'll be happy to help you out.

Actually i solved the problem with a little reaserch, i flashed a differend firmware, and then the pmp rom worked like a charm
Thanks to everyone anyway!

That's a bit of overkill if they just need the modem, unless it's not been separated out of the original full firmware to flash separately, or you need to update the bootloaders.
To dosadnik2001: Which firmware you need depends on which region the phone is from typically. Sometimes other modems from other firmwares work on unlocked phones, but best to stick with what you know should work right first.
What I do not understand is how the baseband firmware and the custom ROM are related?
I've found some post about changing the baseband firmware and there they say that the ROM doesn't care about the baseband, so you should only change it if there are some optimized baseband that can make your network coverage better. On the other side, I found several post claiming that certain ROM is not working because of the baseband firmware version.
Flashing firmware that is not for your region is again questionable for me. Doesn't this going to mess up somehow the microwave part of the phone and you can have some issues with the network carrier eventually?
Thanks.
Hi guys,
I'll receive my S6 Edge in about 3 weeks. Quick question please:
I'm hesitating to root it however, I'll probably want to install a new official ROM (phone i'll receive is from Vodafone but I want a generic Lollipop one).
Is it possible to install a generic Android 5 ROM via Odin via a PC and not root the phone at all?
thnx

Holy **** man... You talk the talk but you defenetly don't walk the walk.
What I'm trying to say is that its way to early to even talk about these things.
First of, we got root but NO custom roms. I don't even know if we have a custom recovery out yet... My guess is no.
And custom Original Samsung ROMs we will have in due time (like Omegaroms and alike)
But custom CM12/AOSP will not happen any where near this half year if ever as Exynos is closed source and most of it has to be hack built. So forget stability too...
Just understand this first before even considering buying the s6 or s6 edge.
I don't think you understood my question here...
I NEVER talked about a custom ROM!! I want to ditch the vodafone ROM and install a generic BAU ROM instead which WILL be available very soon on samfirmware website. And even if it's not available in the next few weeks, it doesn't matter, my question is generic and could fit ANY phones really.
My question is: is it possible to install a BAU ROM without rooting the phone?
Simple, not sure how to explain it further
Ah I get you now. Sorry.
What you are talking about is "unbranding". Yeah that should be easy.
You don't need to be rooted to be able to flash a stock unbranded ROM.
YES! You actually found the word I was looking for and should have used: unbranding! haha SORRY
Yeah, I too thought that I didn't need ROOT to change ROMs if I do it via ODIN and a PC, but I wasn't sure
thnx again!

Actually it is very dangerous (from what I Have been told) to flash any stock firmware via ODIN on any phone except the model it was intended for - that could and probably would brick your phone - IF it was able to flash at all - which is highly unlikely.
I don't know everything - and many here know a lot more than I do - but from what I have read and been told by others smarter than ME _ NEVER try to flash a rom via odin on your phone unless it was specifically made for your model.
Good luck - I hope you find what you what you are looking for.

I would obviously take the unbranded ROM that is specifically made for my phone version and model...
So I got a new galaxy alpha (850F) which is an amazing phone by the way but i have a few questions
1) I noticed that sometimes the signal drops to 0 bars for a few seconds then comes back again, is that normal because of the metal frame or what ?
2)How much does the battery take to charge ?
3) I am still on Kitkat 4.4.4 and the lollipop OTA hasn't arrived where I live yet (I don't think it's coming anytime soon) so what's the best course of action, should I stay on kitkat ? Which official rom can I flash using ODIN ? Is there a toolkit for rooting and installing a custom recovery ?
If there are tutorials for these things I'll be thankful.
Hi Mazika2,
1) I have no idea and never experienced what you describe
2) For me battery charging takes about 1h - 1 1/2h with original charging plug (over USB on PC it takes much longer)
3) You can flash any 5.0.2 ROM via Odin.
Root 4.4.4: You can take Kingroot for example, Knox will not be tripped.
Root 5.0.2: http://www.skyneel.com/2014/09/root-samsung-galaxy-alpha-sm-g850f-by-simple-tutorial.html . Knox will be tripped.
Custom recovery: http://forum.xda-developers.com/galaxy-alpha/orig-development/recovery-twrp-2-8-clockworkmod-recovery-t2923587
Is there anything to reset knox like triangle away ?
I read a few threads about flashing stock firmware, what are modems and hidden.img ?
Which is better in terms of stability , battery, etc... kitkat or lollipop ?
And finally let's say I want to upgrade to stock lollipop using ODIN what are the steps to follow ?
sorry if these questions sound nooby .

1. Issues were noticed on this subject, mainly with 4G network. I changed to 3G and I hadn't more missed calls. I think the problem is more related to inconstant network signal than to the phone itself.
2. With the original adapter is really fast comparing with my old device. I never counted but something like one hour or less.
3. There are people who prefers Kitkat over Lollipop due to better responsiveness. Mine came already with Lollipop so I haven't comparison. For now, I don't have the need to root with custom rom's, the Alpha is superb as it is (except for the annoying touch screen issue...)

Can I flash a SM G850F firmware on a SMG850M?

Knox can't be resetted once it is tripped! Keep that in mind. In terms of stability and battery I would say they are the same. It depends mainly on your daily usage of the phone.

It's complicated, for two reasons I know of, probably more.
1) I'm not sure the chipsets in the F and the M are the same. I know, for example, that the A is Snapdragon and the M is Exynos. I think the F is Exynos, too, but I'm not positive. You'd need the same chipsets for it to work.
2) It's likely the F and the M have different modems, so if you flash F firmware on an M, you may end up corrupting your EFS folder and blacklisting your phone's IMEI on your carrier. You'd need to find out exactly what frequencies the F supports and make sure the M supports them, too. I've read there is a way around this by somehow re-loading two modem files from your phone's original firmware after installing the other phone's firmware, but I've not found step-by-step instructions that are simple enough for me to understand.
Even if those two issues are resolved, it's still dicey. I really want to find SM-G850T firmware and flash it to my SM-G850M, so we are in a similar boat. I can't even find someone who owns a SM-G850T, let alone the firmware. (I did find a question posted on another Site by an individual who said they own a SM-G850T. Unfortunately, half a dozen emails to this individual have remained unanswered.
so here is what I'm planning on doing
1) while on kitkat I'll root with kingroot without tripping knox to backup the EFS folder
2)flash official 5.0.2 using odin
3) try lollipop then decide whether to stay on it or downgrade to kitkat
I just want to know some things before doing the steps above:
1) what are modems and hidden.img in official firmwares ?
2)after rooting on kitkat, can i flash lollipop directly or do i have to flash official kitkat firmware to unroot then upgrade to kitkat ?
I don't know the answers to your questions: I'm even noobier than you!
I do know that when my SM-G850M upgraded to Lollipop, I HATED it. It ran slower and was choppy in the display animations, it cut battery life by at least a third (with no change in anything after wiping the cache), and I especially hated the new color scheme. So, I went back to KitKat. Had to do a Factory Reset to get the phone out of bootloop, but it was fine after that. EXCEPT, the Lollipop downloader reminder stayed on there and I was not able to stop the app or clear the data (those options in the Application Manager were grayed out. So, I flashed the SM-G850M with KitKat firmware from the Dominican Republic (Orange). I read somewhere that Orange was not planning on releasing Lollipop for their Alpha, so I figured this firmware would be Lollipop Downloader Reminder-Free. So far, so good.
